Outstanding Qualities

This unique Japanese maple is one of the few upright laceleaf types. Instead of a low mounding habit, ’Seiryû’ becomes a broad delicate upright vase at maturity. The fine foliage emerges a bright fresh green, then changes to an orangey gold with a red flush in the autumn. A great specimen tree for the urban landscape or beautiful planted in a large container for the patio.

Culture Notes
This upright cutleaf maple develops the best fall foliage color in light to open shade. Japanese maples are surprisingly flexible in their soil requirements. Although they will grow best in a rich well-drained soil, they will also do well in sandy soils and clay. To prevent the fine leaves from burning at the tips avoid hot locations and water the tree regularly during dry weather. Well pruned Japanese maples are an art form in the garden and require an expert touch, so consult an experienced pruner or take local classes before attempting to prune.
